Lisbon Riverfront: Belém to Figueira da Foz Promenade

This 6km one-way riverfront walk starts at Praça do Comércio in central Lisbon's Baixa district, easily reached on foot or by any tram or bus serving downtown Lisbon, with no permit or fee required. The route follows the flat Tagus riverside promenade and cycle path westward, with essentially no elevation gain, on paved and boardwalk surfaces the entire way, offering little shade but constant river breeze. Landmarks along the way include the LX Factory creative quarter, the 25 de Abril Bridge, the Monument to the Discoveries, the MAAT museum, and finally the Belém Tower and Jerónimos Monastery near the endpoint. A natural turn-around point for a shorter walk is the Monument to the Discoveries, roughly 4km from Praça do Comércio, which still covers the walk's most scenic riverside stretch. There are no dedicated water sources along the promenade itself, though cafés, kiosks, and public fountains are frequent in Belém and along the Alcântara docks. The route ends near Belém train station, allowing an easy 15-minute return to Cais do Sodré. The flat, paved surface makes this one of the easiest walks in the Lisbon area, suitable for a wide range of fitness levels.
